EP Energy confirmed it was delisted from the New York Stock Exchange as its shares traded for just pennies.

The Houston oil and gas firm, which is fighting to stay afloat financially, is switching on Friday to trading on the over-the-counter pink sheets and will change its stock ticker from "EPE" to "EPEG."

EP Energy, which focuses on South Texas' Eagle Ford shale and West Texas' Permian Basin, was warned near the beginning of the year that it had six months to develop a plan and regain compliance while continuing to trade on the world's largest stock exchange.
